Description
The SFW file format is associated with Seattle FilmWorks, a photography and film processing company. It was primarily used for images that were developed and digitized by Seattle FilmWorks. The format was proprietary, meaning it required specific software provided by Seattle FilmWorks or compatible third-party applications to view or convert the images. SFW files were popular in the late 1990s and early 2000s, especially among consumers who used Seattle FilmWorks' mail-order film developing service.
Compressed bitmap image that uses wavelet compression instead of the DCT compression used by standard .JPEG images; supports 16-bit color, alpha transparency, and lossless compression.
